Application filed March 14, 1912. Serial No. 683,903.

To all whom t may concern Be it lrnown that I, SWAN OLSON, a citizen ofthe United States, and post office at Marion, Lamour-e county, State ofNorth Dakota7 have invented certain new and use-- ful improvements inrlfrace-Carriers, of

which the following is a specification.

rilhis invention relates to'trace carriers.

'lhe object of the invention resides in the provision of a trace carrierwhich will be simple in construction, cheap to manufacture and whichwill ethciently perform the oilices for which it is intended.

lith the above and other objectsin view the invention consists in thedetails of construction and in the arrangement and combination of partsto be hereinafter more fully described and particularly pointed out inthe appended claim.

In describing the invention in detail reference will be had to theaccompanying drawingswherein like'characters of reference denotecorresponding parts in the several views, and in which- Figure 1 is aperspective view of a trace carrier constructed in accordance with theinvention. Fig. 2, a longitudinal section of the trace carrier; Fig. S,a transverse section taken just forwa 'nl of the pivot of the loclr ingarm of the trace carrier, and Fig. 1, longitudinal section of a slightlymodified form of the invention.

Referring to the drawings the trace carrier is shown as comprising abody 10 provided at each end with a loop 11, said loops being disposedin alinement with each other to permit the passage of a suitable portionof a harness therethrough. Mounted centrally in the body 10 is astud 12which projects on the saine side of the body as the loops 11 and isadapted to be detachably engaged in a perforation in the harness partwhich. passes through the loop 11. When the stud 12 is engaged in aperforation in the harness the trace carrier is locked against slidingmovement thereon, said carrier being at other times capable oflongitudinal adjustment on that portion of the harnessengaged throughthe loops 11. The body 10 is provided at one end with a longitudinalslot 13 and formed on said body on each side oi the slot 13 is an ear14. Bridging the slet 13 is a leaf spring 15 which eX- tendslongitudinally of the body 10 and has one end anchored to said body asat 16. The end walls of the slot 13 are inclined as at 17 engaged by anextension 2Ol sol that when the spring 15 is depressed centrally theinclined end walls 17 of the slot will form a substantial support forsame. Formed on the body 10` at the end thereof remote from the ears 14:is a supporting arm 18 the outer end of which is curved inwardly as at19. Pivotally mounted between the ears '14 is a locking arm 20 which hasits inner end provided with spaced cam eXtensions 21 and 22 adapted forcoperation with the spring 15 as said arm 2O is moved on its pivot.Under normal conditions both of the cam extensions 21 and 22 will engagethe spring 15 andthe latter will thereby serve to hold the free end ofthe arm 20 normally in the position shown in Figs. 1 and 2. To apply atrace within the holder the free end of the arm 20 is moved toward thebody 10 and the cam extension 22 will engage the spring 15 and tensionthe latter. After the trace is inserted in the holder the arm 20 isreleased and the spring 15 will bring the same back to normal position.To remove the trace from the carrier the free end of the arm 2() isforced outwardly or away from the body 10 which will bring the camextension 21 into engagement with the spring 15 and tension the latter.When the trace has been removed the arm 20 is released and the spring 15will react to return said arm to normal position. Movement of the freeend of the arm 2O away from the body 10 is limited by means of a stop 23formed on one ear 111 and adapted to be engaged by a shoulder 24 formedon the arm 20 in a desired position.

In the modiiied form of the invention the outer end of the spring 15 isanchored to the body 10 by a pin 15 and this pin also serves as a stopfor limiting the movement of the free end of the arm 2O away from thebody 10, said pin being adapted to be formed on the inner end of the arm20.

l/Vhat i claim is A trace carrier comprising a body having means forconnection to a harness part and having a longitudinal slot in one end,a supporting arm on the other end 'of the body and directed inwardlythereof, spaced ears on said body on opposite sides of the slotrespectively, a locking arm pivoted at one end between said ears, spacedcam extensions on the pivoted end of said locking arm, a leaf springbridging said slot and coperating with said cam extension to normallyhold the free end of the locking im in" alineder t0 limit themoveiiieilt of the Vlookiiigk ment with the free end of the supportingarm 'in one direction. arm and permitting .pivotal movement ot Y A thelocking arm inV either direction, a shoulv Y v n Y OLSON' der formed enthe outeil edge of the leck- Witnesses:l i ing arm, end a biidgeconnecting said ears C.
